SHOE-CLASP.

SPECIFICATION forming part of Letters Patent No. 313,388, dated March 3,1885.

. ApplioatiOn filed August 12, 1884.

T all whom it may concern:

Be it known that I, JACOB J. UNBEHEND, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Shoe-Clasps, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention has reference to the class of IO shoe-clasps in which aslotted plate attached to one of the flaps of the shoe interlocks with atongue hinged to a plate attached to the other flap; and the inventionconsistsin an improved construction of the last-mentioned plate and itsconnection with the tongue, whereby the manufacture thereof issimplified and the cost of the same materially reduced, and, furthermore, undue pressure on the foot of the wearer of the shoe incident tothe operation of opening and closing the clasp is obviated.

Referring to the annexed drawings, Figure l is a side View of myimproved clasp with the tongue in position for retaining theinterlocking slotted plate. Fig. 2 is a plan view of the same. Figs. 3and 4 are detached plan views of the tongue and its attaching-plate,respectively,and Figs. 5 and 6 illustrate modifications of theconstruction of the latter.

Similar letters of reference indicate corre- 3o sponding parts.

A denotes the usual transversely-slotted metal plate designed to beattached to one of the flaps of an Arctic overshoe. Bis another metalplate adapted to be secured to the other flap of the shoe, and 0represents the tongue which is hinged on the plate B and adapted toenter one of the slots of the plate A, and effectually interlock withsaidplate by drawing it over onto the plate B, as represented by 0dotted lines in Fig. 1 of the drawings.

The connection of the tongue 0 with the plate B, I form as follows, towit: The plate B,I provide with two eyes or pintle-bearings, b b, aproper distance apart to receive between 5 them the end of the tongue tobe hinged thereon, and at the outside of said eyes I provide the platewith elastic lips or spring extensions e e, which are integral with theplate and formed by longitudinal slits c c in theend of the plate B, atthe outside of the aforesaid (No model.)

eyes or bearings b b, as shown in Fig. at of the drawings. The tongue 0,I provide with a pintle, a, which may be either integral therewith orrigidly attached thereto in any suitable manner. Said pintle projectsfrom opposite edges of the tongue, and the ends thereof extend throughthe eyes I) b,and across the elastic lips e e, and are flattened orangular in crosssection in such a manner that when the tongue lies uponthe plate B, as shown in Fig. 1 of 6 the drawings, one of the flat sidesof the pintle lies upon the elastic lip. In raising the free end of thetongue the angles of the pintle which turns with the tongue exerts adownward pressure on the lips e c, the resistance of which serves toautomatically hold the tongue in its aforesaid position upon the plateB, and also throw the tongue into its distended or open position afterthe same has passed over the center of its movement. 7c

By the employment of the flattened or angular pintle in lieu of the camformed on the tongue, as heretofore constructed, I materially reduce thecost of manufacture, and also relieve the'wearer of the shoe of unduepressure'of the spring upon the foot in the opera tion of opening andclosing the clasp, inasmuch as the pintle is above the plane of theplate B, while the cam formed on the tongue as heretofore is necessarilymore or less below the said plate or projects more or less from the axisof the tongue. I do not, however, limit myself to the specificarrangement of parts just described, as it is obvious that the flattenedor angular hinge-pin may be rigidly attached 8 5. to or made integralwith the plate B, as shown in Fig. 5 of the drawings, and the tongue 0formed with a sleeve, 5, by which it is hung on the hinge-pin, and withelastic lips e at the sides of the sleeve, as represented in Fig. 6 ofthe drawings, said lips pressing on the hinge-pin when the parts areunited.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. The combination, with the tongue 0 and plate B, of a flattened orangular pintle, by which the tongue is hinged on said plate,.andspring-lips on either the tongue or plate bearing on the aforesaidpintle to receive the im- 100 pingement of the angles thereof whenswing- In testimony whereof Ihave hereunto signed ing the tongue backand forth on the plate, my name and affixed my seal, in the presencesubstantially as set forth and shown. of two attesting witnesses, atSyracuse, in the 2.
